<p class='vspace'></p><h2>String()</h2>
<h4>Description</h4>
<p>Constructs an instance of the String class.  There are multiple versions that construct Strings from different data types (i.e. format them as sequences of characters), including:
</p><ul><li>a constant string of characters, in double quotes (i.e. a char array)
</li><li>a single constant character, in single quotes
</li><li>another instance of the String object
</li><li>a constant integer or long integer
</li><li>a constant integer or long integer, using a specified base
</li><li>an integer or long integer variable
</li><li>an integer or long integer variable, using a specified base
</li></ul><p class='vspace'></p><p>Constructing a String from a number results in a string that contains the ASCII representation of that number.  The default is base ten, so
</p>
<p class='vspace'></p><p>
<pre>
String thisString = String(13)
</pre> 
</p>
<p class='vspace'></p><p>gives you the String "13".  You can use other bases, however.  For example, 
</p>
<p class='vspace'></p>
<pre>
String thisString = String(13, HEX)
</pre>
</p>
<p class='vspace'></p><p>gives you the String "D", which is the hexadecimal representation of the decimal value 13. Or if you prefer binary, 
</p>
<p class='vspace'></p><p>
<pre>
String thisString = String(13, BIN)
</pre>
</p>
<p class='vspace'></p><p>gives you the String "1101", which is the binary representation of 13.
</p>
<p class='vspace'></p><h4>Syntax</h4>
<p>String(val)<br />String(val, base)
</p>
<p class='vspace'></p><h4>Parameters</h4>
<p>val: a variable to format as a String - <em>string</em>, <em>char</em>, <em>byte</em>, <em>int</em>, <em>long</em>, <em>unsigned int</em>, <em>unsigned long</em><br />base (<em>optional</em>) - the base in which to format an integral value
</p>
<p class='vspace'></p><h4>Returns</h4>
<p>an instance of the String class
</p>
<p class='vspace'></p><h3>Examples</h3>
<p>All of the following are valid declarations for Strings.
</p><pre>
String stringOne = "Hello String";                     // using a constant String
String stringOne =  String('a');                       // converting a constant char into a String
String stringTwo =  String("This is a string");        // converting a constant string into a String object
String stringOne =  String(stringTwo + " with more");  // concatenating two strings
String stringOne =  String(13);                        // using a constant integer
String stringOne =  String(analogRead(0), DEC);        // using an int and a base
String stringOne =  String(45, HEX);                   // using an int and a base (hexadecimal)
String stringOne =  String(255, BIN);                  // using an int and a base (binary)
String stringOne =  String(millis(), DEC);             // using a long and a base
